What salary you'd need in Milwaukee
To maintain your Chicago purchasing power, here's what you'd need to earn in Milwaukee.
Chicago vs Milwaukee: which makes more sense for you?
On paper, Chicago's cost-of-living index of 112 runs roughly 14.3% higher than Milwaukee's 96. But that headline number papers over real differences in how that cost is distributed — rent might be far more expensive while groceries and transit costs run closer to even.
The rent gap
A 1-bedroom apartment in Chicago averages $1,700/month, vs $1,300/month in Milwaukee — a -$400 difference. For 2-bedrooms, the gap widens to -$500/month. Over a year, the rent difference alone is $4,800 on a 1-bed.
Income context
Median household income in Chicago is $58,984, while Milwaukee runs $51,234 (-$7,750 difference). That matters for how the cost-of-living gap actually feels day-to-day — if local salaries are also higher, the cost difference washes out partly. If local salaries lag the cost-of-living gap, your paycheck buys noticeably less.
State tax differences
Chicago is in Illinois and Milwaukee is in Wisconsin, so you'll also pick up a state-tax difference. Tax-free states like Texas, Florida, Tennessee, Washington, and Nevada deliver real take-home upside even when nominal salaries are similar.
